Specification of Letters Patent.

Patented July 5, 1921.

Application filed September 25, 1920. Serial No. 412,753.

To all whom it may concern.

Be it known that I, VVILLIAM K. HARRIS, a citizen of the United States, residing at Salem, in the county of Salem and State of New Jersey, have invented certain new and useful Improvements in Linoleum or like Printing Machines, of which the following is a specification.

In printing rugs on linoleum and like printing machines, short rugs are inevitably made because of defects in the carpet or material upon which the printing is done, and in order to preserve the timing of the machine it has been heretofore necessary to print two short rugs in succession although the defect might require the printing of but one short rug, and this resulted in the pro duction of a large number of short rugs which are not readily salable and which in fact often approach waste.

The principal object of the present invention is to provide for printing short rugs singly, and not in succession in pairs, there by reducing the number of short rugs produced by at least a half.

To this and other ends hereinafter set forth, the invention, stated in general terms, comprises manually operatable means for advancing or retarding the cycle of the action of the cams, which control the printing operation of the blocks, in respect to the carpet feed mechanism of the machine, so that the annular setting of the cams can be adjusted even while the machine is in operation to change the timing of the cycle of printing operations of the blocks in respect to the carpet feed and to the other operations of the machine.

The invention further comprises the improvements to be presently described and finally claimed.

In the accompanying drawings forming a part here0f- Figure 1, is a transverse sectional view of one form of mechanism embodying features of the invention.

Fig. 2, is a top or plan view of the same.

Fig. 3, is a view of the righthand end of F ig. 2, and I Fig. 4;, is a detail view of one of the parts detached.

In the drawings 1, is a cam shaft. It is a usual provision of linoleum and like printing machines and it is driven from the machine and its revolutions are timed with respect to the general feed and operation of the machine. 2, is a block releasing and detaining latch shaft of which several are provided and they are usual provisions of such machines. The movements of these shafts 2, are controlled from the shaft 1, and sometimes additionally by hand, and their function is to detain and release printing blocks to operate the latter in various orders. For those desiring information about a specific example, reference may be made to my Pat ent No. 1,333,308 of March 9th, 1920, in which the part, herein designated cam shaft, is shown, and in which the parts, herein designated latch shafts, are also shown. 3, is a cam revoluble in respect to the cam shaft 1, and ada )ted to operate the latch-shaft 2, as shown, t irough the instrumentality of an arm 3 or more accurately a roller fir, on the arm 3*. 5, is a collar revoluble with, or fast on, the cam shaft 1, and provided with spaced keeper elements 6, shown as pits in a keeper-plate 8, detachably mounted in the collar 5, by means of screws 9, so that plates with differently arranged pits can be interchangeably employed. 10, is a hand wheel revoluble on the cam shaft, or more accurately, on an extension of the hub of the cam 3. 12, is a spring pressed bolt carried by the hand wheel and adapted to lock the cam to the hand wheel for revolution thereby or to the collar and shaft 1, for revolution therewith. 13, is a V-shaped cam on the hand wheel and by operating on a roller 14, on the bolt 12, it serves to retract and project the latter into one or the other of the pits 6, and it also serves to connect thecam and hand wheel.

In use after a short rug has been printed, the operator by turning the hand wheels 10, can adjust the angular positions of each of the cams 3, and so change the time of the order of the operation of the printing blocks that another short rug is not made, instead a regular full length rug is made.

It will be obvious to those skilled in the the combination i of adriven cam-shaft,

7' blo clereleasing and detaining latch shafts,

cams freely revoluble in-respect to the cam shaft, and' adapted to operate the latch shafts, collars revoluble ith the cam shaft and provided with spaced keeper elements, hand-Wheels revoluble in respect to the cam shaft, spring bolt elements carried by the hand-Wheels and adapted to lock the camsto the collars to be driven thereby, and to the hand wheels to, be turned thereby, and cam means on the hand Wheels for operating the bolt elements by movement of the hand Wheels,substantially as described.\

2. In a linoleum or like printing machine the combination of block-releasing and detaining latch-shafts, a cam shaft common to the latch-shafts, cams revoluble on the camshaft and adapted to operate the latch-shafts in predetermined order, and hand Wheel mechanism for-coupling and uncoupling the 1 cams and cam-shaft in different angular relations to change the timing of the'order of operation of the latch shafts in respect to the camshaft, substantially as described;

3. In alinoleum or like printing. machine the combination of block-releasing and detaining latch-shafts, a cam shaft common to thelatch-shafts, cams revoluble on the cam "shaft, collars fast .on thecam-shaft, keeper:

the combination of block-releasing and'de-f' 40 r taining latch shafts, a cam shaft common to the latch shafts, cams revoluble onthe cam shaft, and manual means for changing the angular setting ofthecams in respect tothe stantially-as described.
